Towards near real time high-resolution Dopplergrams from GONG

The GONG network, consisting of six sites around the globe, provides continuous observations of the Sun. The processing and merging of Dopplergrams from various sites usually takes several months before these are made available to the community for analysis. In this paper, we discuss our recent atte...

Description
Summary:The GONG network, consisting of six sites around the globe, provides continuous observations of the Sun. The processing and merging of Dopplergrams from various sites usually takes several months before these are made available to the community for analysis. In this paper, we discuss our recent attempts to reduce the delay between observations and the availability of merged Dopplergrams. Our analysis indicates that the modified approach does not influence mode parameters and inferred helioseismic flows. However, the duty cycle plays a significant role in inferring the sub-surface flows and a low duty cycle, if less stations contribute, may lead to qualitatively different results.
